Cache-problems even without using forms

[phpbuild-it]

I have the following 2 scripts

/* Script 1 **/

<?

header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Datum in het verleden
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT"); // Altijd veranderd
header("Cache-Control: no-store, no-cache, must-revalidate"); // HTTP/1.1
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");

// Note the variable issue_id
session_unregister("issue_id");
unset($issue_id);

<a href="script2.php?issue_id=1">Scipt 2</a>
<a href="script2.php?issue_id=2">Scipt 2</a>

?>

/* Script 2 **/
<?

// Note the variable issue_id
session_register("issue_id");

echo "issue_id";

<a href="script1.php>Scipt 1</a>

?>

When I click on the first href link, it will display "1" correctly. Afterwards, pressing the Back Button of IE, and then clicking the second href, it still displays "1"!!! :mad:

It only displays the correct issue_id when I click into Script 1! It works without any problems locally but not on my Linux setup.

Could the problem be "HTTP_CACHE_CONTROL = max-age=259200"? This is on my Linux setup. If so how can I change the setting? I have looked in my php.ini and httpd.conf but no luck.

Thanks in advance

You seem to be missing a call or two to [man]session_start[/man]. That might be it. I'm not sure; the code you posted isn't the code you're using (I can tell; echo "issue_id" would echo "issue_id", not "1". 🙂).

Sorry for! I have broken my code into two simple scripts, here they are:

/* Script 1 **/

<?

session_start();

header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Datum in het verleden
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT"); // Altijd veranderd
header("Cache-Control: no-store, no-cache, must-revalidate"); // HTTP/1.1
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");

session_unregister("issue_id");
unset($issue_id);

echo "<a href='cache2.php?issue_id=1'>cache 1</a><br>";
echo "<a href='cache2.php?issue_id=2'>cache 2</a><br>";
echo "<a href='cache2.php?issue_id=3'>cache 3</a><br>";

?>

/** Script 2 */
<?

session_start();
session_register("issue_id");

echo "$issue_id<br>";

echo "<a href='cache1.php'>cache</a>";

?>
